Police in northwestern China are offering a 2,000 yuan (US$300) reward for information about a motorcyclist alleged to have been involved in a “hit-and-move” incident involving a five-year-old boy, local media reported.

The incident happened on a rainy day last week in Hanzhong, Shaanxi province, as the child was playing in the street while his mother sold noodles at a nearby market, Huashang Daily reported on Sunday.

According to a watermelon vendor who claimed to have witnessed the event, the motorbike knocked the boy down and rolled over his leg. After the crash, the child was unable to stand up and his face was covered in blood, the report said.

The boy told onlookers that his mother was working nearby, but after about 10 minutes of no one coming to take care of him, the motorcyclist was instructed to call an ambulance. He instead said he would take the child to hospital on his motorbike, and rode off with him.

Earlier this month, a woman in Harbin, capital of northeast China’s Heilongjiang province, was charged with suspected murder after knocking down an elderly man while driving her tricycle.

With the help of three male friends, the woman then drove the victim several kilometres away from the scene of the crash and left him to fend for himself. The man later died from his injuries and the four suspects were arrested, local media reported at the time.
